抗战前期确实没法打，连级战斗都没希望。国民党的60迫击炮1941年才造出来。

八九式掷弹筒所配用的榴弹实际装药量约150克梯恩梯型炸药，相比较苏德同类型的轻型迫击炮装药量都在90克左右，美军的M1型60毫米迫击炮则装药量115克——换言之八九式掷弹筒的装药量甚至比口径比它大一圈的美军60迫还要多出一大截。考虑到苏德轻型迫击炮榴弹装药为硝酸铵型炸药，其杀伤威力比八九式又要弱一大截。美军1943年实测八九式掷弹筒，发现八九式掷弹筒的弹片数量、杀爆范围都远好于M1型迫击炮。因此，八九式掷弹筒关键性能其实很强。
军盲，你看德军150mm步兵炮二战中后期还用吗？

The only major design difference between the 57 and 75 that would emerge was the recoil system. But, in 1890, even before the 57 entered testing, General Mathieu, Director of Artillery at the Ministry of War, had been informed that Konrad Haussner, a German engineer working at the Ingolstadt arsenal, had patented an oil-and-compressed-air long-recoil system. They also learned that Krupp was considering introducing the system after testing it. Krupp would later reject Haussner's invention, due to insoluble technical problems caused by hydraulic fluid leakage.

It took five more years under the overall leadership of Mathieu's successor, General Deloye, to perfect and finally adopt in March 1898 an improved and final version of the Deport 75 mm long-recoil field gun. Various deceptions, some of them linked to the Dreyfus Case which erupted in 1894, had been implemented by Deloye and French counter-intelligence to distract German espionage.[5]

Captain Sainte-Claire Deville also designed important additional features, such as a device for piercing the fuzes of shrapnel shells automatically during the firing sequence (an "automatic fuze-setter"), thus selecting the desired bursting distance. The independent sight had also been perfected for easy field use by the crews, and a nickel-steel shield was added to protect the gunners. The armored caissons were designed to be tilted in order to present the shells horizontally to the crews. The wheel brakes could be swung under each wheel ("abattage"), and, together with the trail spade, they immobilized the gun during firing.The gun was officially adopted on 28 March 1898 under the name "Matériel de 75 mm Mle 1897". The public saw it for the first time during the Bastille Day parade of 14 July 1899.
土共三发迫击炮，炸死安培规秀。
当时大一些的军阀, 比如奉系, 晋系, 桂系, 老蒋的江浙系等都能造迫击炮吧?
主要还是军阀割据,各自为政, 未能形成合力. 其它军阀的财力有限, 造不了太多. 老蒋的江浙系比较有钱, 但是内部极度腐败, 买办当家, 不干实事, 信奉造不如买, 因为买洋货的回扣比较高.

本子二战迫击炮上是落后的，连中国都不如。60迫射速精度比掷弹筒强太多了。
既没有炮钢，也没有炮镜。1941年从美国买到炮钢，1944年才仿制出美式60迫击炮的瞄准镜。
